Now a days any modern portable electronic device has almost exclusively multilayer ceramics capacitors in it. In a typical cellphone, hundreds of these little critters as small as 0.3mm width to 0.6mm length are all over the main PCB (Printed Circuit Board) . So it seem like they have no drawback and easy to drop into where there is a capacitor needed. I made following graphic to remind myself that may not be the case. Note following diagrams only apply to class 2 type which are most commonly found.

Why MLCC’s are useful?

When does a MLCC become problematic?

The above are little handy charts which could be used on a engineering virtual wall.
